Electron transfer is the term for this process. The resulting anion and cation are attracted by Coulombic forces and an ionic compound is formed. Ionic compounds are neutral: the number of electrons lost in forming the cation(s) must equal the number gained in forming the anion(s). For example, Aluminum (Al, Z = 13, Group 3A or 13) will lose 3 electrons to become Al3+ which is isoelectronic with Neon (Ne), its closest noble gas. To form an ionic compound those...
